and the like with spiral metallic hose. The

metal tape used for forming the hose is of figured section and is wound-spirally upon itself, in a well known manner, and the invention is-that in winding the tape a r1g1d member is introduced between the windmg-rollers and the cable. In this manner the cable is relieved of the pressure of the roller acting upon the of the tape being wound on, where cable is protected from Apparatus suitable for carrying out my invention is illustrated in the accompanyinfi drawing, and it is assumed that a meta 1 gortion y the c hose winding machine is em loyed in in which the so-called windingead rein a well-known manner, the cable that is through it.

Figure 1 is an elevation and part section the winding-head as is of the present ental end eleshowmg so much of requisite for the disclosure invention. Fig. 2 is a fra vation of the winding hea end elevation and Fig. 4 a vice for relieving the cable o inafter desi ated the winding-tongue.

a is the winding-head, which is driven by the hollow 'shaft (1, and which presents a drum 0. adapteed to receive the metal tape which is to spirally wound. The tape passes from the drum a? to the windingrollers 0, c c, which may be under resilient pressure, for instance acted upon by springs h in a well-known manner. The central aperture of the winding-head, a receives a tubular member b (Figs. .3 and 4), which rotates with the head a and presents a suitably bent-terminal projection d, which extends u to the plane of motion of the winding-r0 ers and which I des' ate the 9 wind"- ing-tonguel This tongue serves as a suplan of the dcto be armored being fed Fig. 3 is an ressure, hereport for the roller 0 which guides thepiece of tape bein wound onto the cable g, so that this ro er 0 does not bear directly against the cable, but merely against the tongue d.

To provide support for the two sup mentary rollers and 0 the latter are rnished with discoidal checks 6, which bear upon the cylindrical portion f of the tubular member b.

By means of my new device it is obvious that injury to the cable or the like by the metal tape being wound on is wholly obviated, despite the fact that the armor can be wound as tightly as is possible around the cable, so that shifting of the cable and its armor relatively to each other is practically impossible.

Havin thus described my invention, I declare tfiat what I claim as new and desire to secure by Letters Patent is- 1. In combination a winding head with winding rollers thereon for spirally winding metal bands on cables, a hollow shaft in the winding head, one or more rigid supporting members directly in front of the hollow shaft and introduced between the cable and the winding rollers for supporting the rollers as the 'metal bands are wound on to the cable and thereby relieving the cable of the pressure of the rollers and preventing the cable being damaged thereby.

2. In a machine for armorin cables and the like with spiral metallic hose, a. centrally perforated rotatable winding-head, a tape-guiding roller, and supplementary rollers each resenting a cheek, mounted on the head an rotating also on their own axes, and a tubular member fitting the hole in the head and presenting a bent tongue dpro'ecting into the plane of motion of sai ;ro lers and adapted to receive the pressure of the tape-guiding roller and also presenting a part onwhich the checks of the sutpplementa? rollers bear, substantially as escribed.

n witness whereof I have hereunto signed name this 8th day of March 1909, in the of two subscribing witnesses.
